CT Mail Mod

This is by the same creators as CTRAID.
...no, wait, please don't run away! Hear me out!

CT Mail Mod gives you several new abilities on your mailbox.

Firstly, it adds the ability to open every single mail you have, and grab all of the attachments. Just brought a ton of stuff on the auction house? Just mailed a ton of stuff from your alts? You can now open everything all at once automatically, rather than having to slowly click one at a time.
(Admittedly it does still take the same time, but you can don't have to be there waiting for the sever lag to go away and repeatedly clicking ^_^)

The second thing it gives you is the ability to send more than one attachment with a mail. You get a bag like screen, where you drag and drop everything in that you want to send. Type in the person's name who you want to send it to, press go, and it'll send everything at once.
How does that work? Well, it's actually sending one mail per attachment. So what's the point? It saves you a lot of time doing it for yourself!

I love this addon ^_^

Been using this addon for months, and would feel completely naked without it! The ability to open all mails and send several mails in one go is so great.

Btw what I was going to say was that you don't have to drag and drop items into the mail-'bag', just Alt-click the items you want sent, and they get added instantly.
